Analysis of the Friction Factor chart above shows that each of the six stocks mentioned above have high net dollar losses (Change) and extremely low price friction in their stocks. The Friction Factor displays how many more shares of buying than selling are required to move a stock higher by one cent or how many more shares of selling than buying moves a stock lower by 1 cent.

For example, the chart above shows ISRG with a dollar loss this morning of -$7.12 and a Friction Factor of -39 shares. That means that it only takes 39 more shares of selling than buying to move ISRG lower by one penny. This means the Market Makers are allowing the stock to drop quickly (low friction). The combination of low friction and negative market direction can drive prices lower faster than normal.

About BUYINS.NET

WWW.BUYINS.NET is a service designed to help bonafide shareholders of publicly traded US companies fight naked short selling. Naked short selling is the illegal act of short selling a stock when no affirmative determination has been made to locate shares of the stock to hypothecate in connection with the short sale. Buyins.net has built a proprietary database that uses Threshold list feeds from NASDAQ, AMEX and NYSE to generate detailed and useful information to combat the naked short selling problem. For the first time, actual trade by trade data is available to the public that shows the attempted size, actual size, price and average value of short sales in stocks that have been shorted and naked shorted. This information is valuable in determining the precise point at which short sellers go out-of-the-money and start losing on their short and naked short trades.

BUYINS.NET has built a massive database that collects, analyzes and publishes a proprietary SqueezeTrigger for each stock that has been shorted. The SqueezeTrigger database of nearly 2,550,000,000 short sale transactions goes back to January 1, 2005 and calculates the exact price at which the Total Short Interest is short in each stock. This data was never before available prior to January 1, 2005 because the Self Regulatory Organizations (primary exchanges) guarded it aggressively. After the SEC passed Regulation SHO, exchanges were forced to allow data processors like Buyins.net to access the data.

The SqueezeTrigger database collects individual short trade data on over 7,000 NYSE, AMEX and NASDAQ stocks and general short trade data on nearly 8,000 OTCBB and PINKSHEET stocks. Each month the database grows by approximately 50,000,000 short sale transactions and provides investors with the knowledge necessary to time when to buy and sell stocks with outstanding short positions. By tracking the size and price of each montha�s short transactions, BUYINS.NET provides institutions, traders, analysts, journalists and individual investors the exact price point where short sellers start losing money and a short squeeze can begin.
